' Serial No. 346,065.

To to whom, it may cancer/1 Be it known that I, CLARENCE WioKns,

a citizen of the United States, residing at (lamdcn, in the county of Camden, in the 3 State of New Jersey, have invented certain new and useful Improvements in Methods of Removing Labels from Records ,for Talking- Machines, of which the following is a speciiication.

This application is a division of the application filed by me on October 6th, 190.5,Serial No. 2S1,598,for improvements in apparatus for removing labels from records for talkingmachines.

My invention consists general l y in a method by which labels, which have been impressed in the records of talking machines, may be removed therefrom for any purpose; as for inst'ance,.for the purpose of remolding or having therein any admixture of foreign matter.

My invention consists more specifically in softening record labels and by subjecting the 2 5 softened label to the action of rapidly rotating cutters which remove the label from the record.

In view of the foregoing, the object of the present invention is to cheaply and re iidly remove the labels impressed into talking machine records; to remove the same by the action of cutting blades; and to so soften the label while it is being subjected to the action of the cutting blades that the cutting edges of the blades are not materially dulled by the normally hard material of the label.

In the accompanying drawings forming a part of the specification, Figure 1 is a perspective View of one form of the apparatus employed by me in carrying outthe objects of my present invention; Fig. 2 is an elevational view of the cutter and its supporting spindle, parts thereof being shown in section; Fig. 3 is a plan view of the face of my improved cuticr; and Fig. 4 is a sectionulvimv taken lengthwise of one arm of my improved cutter head.

In the drawings, in which similar numerals of reference indicate similar parts throughout the several views, 1 indicates a suitable base upon which a table 2, adapted to sup; port'the disk 3, from which the label t is to reforming the material of the record without be removed, is mounted Secured to the base 1, is a bracket 5, to the top of which a lover 6 is pivoted, a lu or suitable projection 6 on the under side oi said lever (i forming a clamping point between which and the table the disk maybe securely held while the label is being removed.

Above the table 2, and in axial alincment therewith, is located a vcr .al :spindlc 7, the lower portion of which spindle is provided with an axially arranged comluit'il, and with a tapered end 9, terminating in. aih ruled portion 10, which enter the hub ll, of the culter 12 a'nd by which said head is secured to the spindle. At a suitable distance from its lower end, the spindle 7 is provided with a collar 13, the face of which is provided wit h a groove 14, which. communicates by suitable passages 15 with the upper end of the conduit 8. The spindle 7 is tapered at its upper end. as at 16, and terminates in. the head '17, the tapered portion and head being adapted to lit a suitable socket, not shown, by which. the spindle may be rotated and also moved in the direction of its axis toward and away from the table 2. V U

The collar 13. is adapted to be incloscd by a suitable stufling box its, which consists of the main or body portion 18, the upper end of which is internally threaded, and the follower 19, the topof which is provided with a suitably notched. head 20. The body portion, 10, of the stulling box, is furthdr providcd with an upwardly extending spring 21 adapted to engage the notches 20" in the head 20 of the follower l9 and to hold the l'ollmvcr from rotating with respect to the stulling box. Within the stuiiing box and located on either side of the collar 13, are packing 'ashers 22, which are forced into steam tight cugagemcnt with the collar 1-; by the follower 19 of the stulling box. The stulling box is further provided with an opening 23, the in ner end of which communicates with the pas sage formed by the groove 14 and the inte rior of the stulling box, and the outer end of which is adapted to be attached to a pipe. 24, connected with a suitable supplv of steam. By thisarrzuigemcntit will be apparent that steam may be supplied through the pipe 24, opening 21%, groove 14 and openings 1:") to the conduit 8 in the lower end of the spindle,

'Theicutter head 12 consists of the hub portion 11 and four radial arms 25, the front face of each'arm being adapted to have secured theretomnt ter blades 26. These blades may be secufed to the arms in any suitable mafii'ier, as by screws 27, and the blades may .be set into the face as shown in Fig. 1.

The cutter head is provided with a central chamber 28 which communicates with the conduit 8 of the spindle and with chambers 29 running longitudinally of the radial arms. Prgferably, I form the chambers 29 by d'riliing from the outer end of the arm into the chamber 28, and then close the outer end of the holes so made, in any suitable manner, such as by the screw plug 30. The backs of the arms on the sides opposite the faces to which the blades are secured, are preferably beveled to form faces as indicated by 31, the

beveled face of each arm being so arranged that the thickness of the material between the outer end of the chamber 29 and the face 31 is considerably less than the thickness nearer the axis of the cutter head, the purpose of which construction will be described later.

Through the beveled faces 31 of the arms 25, a series of jet passages 32, communicating with the chambers 29, are formed, as plainly shown in Fig. 4, and the bevel of the face 31 will make the length of the passages 32 constantly increase in a direction toward the axis of the cutter head. The an le which the jet passages 32 make with the chamber 29 is such that the steam passing from the central chamber 28 through the radial chambers 29 g label, and the label may be so rapidly re and the jet openings 32, will be directed immediately in advance of the edge of the suc-.

ceeding cutter. 1

As is well known, the velocity with which fluids will be discharged through passages of equal diameter but of different lengths, will inversely vary as the length of the passages, since the friction between the fluid and the walls of the passages will have the greater effeet on the fluid passing throu h the longer passage.

In chambers, like t e chambers with which the radial arms of the cutter head are provided, in which the fluid is supplied to the chamber from one end and is discharged at diflerent distances from the point at which the fluid is supp-lied to the chamber, the

tendency of the fluid would be to discharge more rapidly through the passages nearest the supply unless some adequate means for compensating for this were employed.

In order to effect a more equal discharge of steam from the jet passages independent of their distance from'the source of steam supply, I have so beveled the faces 31 of radial arms that the steam issuing from the jet openings nearest the axis of the spindle, and consequently nearest the point at'which the steam is supplied to the chamber, will have to traverse longer passages than that issuing through the jet openings nearer the ends of ghe arms. This feature is plainly shown in ig. 4.

The cutter head is provided with a center ing pin 33, adapted to cooperate with the opening in the center of the disk.

Since the labels are usually depressd a Jittle below the surface of the records, I preferably arrange the cutting edges of the blades 26 so that the portion thereof nearer the axis of the head, asat 34, will cut deeper than at the ends, as at 35.

The operation of my device is as follows i-- The disk 3, being placed inposition on the table 2 and clamped thereto by the lever 6, the cutter head is put into rotationand steam is supplied through the pipe 24." The cutter, head is then lowered, the centeringpin 33 entering the opening in the center of'the disk 4, and the blades are forced againstjthe surface of the label' l. The s-teamissuing'gfrom the jet passages 32 will impinge the labeljust in advance of the succeeding cuttinggblade and will so soften the label at the point where it is engaged by the edge of the cutting blade that the cutter will cut or are thc'label with-- out destroying the edge 0 the blade, and this will continue until the entire label has been cutthrough, when the outer ends of the blades will engage and smooth the surface of the record adjacent the depression in which the label is placed. The cutter head is then raised, and other records may then be treated in the same manner.

From the above it will be apparent that the steam is so directed that it impinges only the moved that the material. of the record does not have time to be materially affected by the heat thereof. Thus I rapidly and ef-,

which is easily affected by heat, without destroying, mutilating or materially affecting the records into which the labels have been impressed.

Having thus described my invention, what I claim and desire to protect by Letters Patent of the United States, is

1. A method of removing labels impressed into a mediumwhich is easily affected by heat, which consists in softening the surface of the label and immediately cutting away the softened portion thereof.

2. Themethod of removing a label impressed into a medium easily affected by heat, by simultaneously subjecting the label to the action of steam, and cutting away the same.

3. A mpthod of removing'labels impressed into a n'iedium which is easily affected by "heat, which consists in steaming the surface of the'label Without substantially softening the supporting medium, and cutting away the steamed portion of the label.
